ChatGPT code hints at a $600 monthly Pro Max plan

Developer Tibor Blaho found PROMAX-related fields in the ChatGPT web source code. He believes OpenAI may be preparing a higher-tier ChatGPT Pro plan, possibly costing $600 per month. OpenAI has not officially announced this plan or confirmed whether the code relates to a future product, so the name, features, and final price remain uncertain.

OpenAI has been adjusting ChatGPT's subscription system in recent years, offering Plus, Pro, and various paid plans for businesses and teams. It previously paused the $200 ChatGPT Pro subscription to ease system pressure and keep the service smooth for more users.
